Material: High Borosilicate Glass, with Flow Control-Airflex Nipple. The Little Lookers brings to you exclusive Baby Feeding Bottle featuring Premium quality High Borosilicate Glass. By nature, glass is free of BPA — you don’t have to worry about different types of plastic and whether or not they’re safe. Glass is also easy to clean, and glass bottles can be easily sterilized in boiling water. If you want a non-toxic baby bottle, you can’t go wrong with glass. A reason why many drinks are still stored in glass containers is because plastic bottles tend to impart various flavours into liquids including breastmilk or infant formula especially when heated. Purity of taste is a major concern for many mums who only want the best for their babies. Glass baby bottles do not affect the taste of milk and preserves the natural flavour of infant milk formula or fresh milk expressed through breast pumps.
